case class Lookup(from: String, localField: String, foreignField: String, as: String) extends PipelineOperator with Product with Serializable
_Since MongoDB 3.2:_ Performs a left outer join to an unsharded collection in the same database to filter in documents from the "joined" collection for processing. https://docs.mongodb.com/v3.2/reference/operator/aggregation/lookup/#pipe._S_lookup
